Powers:Presumably Blackball's powers were very similar to that of the real Speedball's.

Bio:The evil doppelganger of Speedball that appear during the Infinity War crisis. After destroying many homes in Connecticut (the area that Speedball was living at the time) in search of Speedball's mother, he finally found her in her new home in Springdale. Blackball was ready to attack when the real Speedball came crashing in. The two did battle, and in the end, the real Speedball lashed out at Blackball with his kinetic energy, destroying it.

Notes:Was referred to as Dark Speedball on the cover of New Warriors #27, and as Blackball in the dialogue contained within the issue.
